Solution
The correct answer is "help the cell interact with its external environment". Transmembrane proteins play a crucial role in interacting with the cell's external environment. They can act as gateways for ions and other molecules to enter and exit the cell, and they can also receive signals from the environment and transmit them into the cell. This helps the cell respond to changes in its surroundings.
